CAR -COUPLING.

SPECIFICATION forming part of Letters Patent No. 365,366, dated June 28,1887. Application filed March 28, 1887. Serial No. 282,772. (No model.)

To all whom it may concern:

Be it known that I, SAMUEL RUDOLPH COPELAND, a citizen of the UnitedStates, residing at Huron, in the county of Beadle, Dakota Territory,have invented a new and useful Improvement in Oar-Couplings, of whichthe following is a specification.

My invention relates to improvements in car-couplings; and it consistsin certain novel features, hereinafter described and claimed.

In'the accompanying drawings, which fully illustrate my invention,Figure 1 isa perdistant from the center of said block. 1

spective view showing the end of a car provided with my improvedcar-coupling. Fig. 2 is a vertical longitudinal section showing twocouplers together. Fig. 3 is a detail perspective view of the combinedlink and coupling-pin; and Fig. 4 is a detail perspective view of theslotted plate which is placed over the pivotal connection of the pin andlink. 7 Referring to the drawings by letter, A designates the end of acar, having the draw-head B secured to the bottom thereof in the usualor any preferred manner. The bottom of the draw-head is provided with alongitudinal slot, 0, which extends from its mouth to near the rear ofthe same, and communicates with the open interior of the draw-head. Thecoupling link works in this slot, as will be hereinafter described, andthe upper side of the draw-head is provided near its front end with asimilar shorter slot, D, through which the coupling-pin entersthe'draw-head. The upper side of the draw-head, near. the rear endthereof, is recessed, the front and rear walls of said recess beinginclined up and backward in parallel planes. Afilling-block, E, isplaced in this recess, and has the inclined or beveled edges e, to fitagainst the inclined walls of the recess. The fillingblock is provided,also,with two longitudinal slots, F, nearto and equi- G is thecoupling-pin, which is formed in the are of a circle, as shown, and hasthe arm H extending rearward from its upper end. The arm H terminatesover the slots F, andis so formed as to provide the depending lugs orears I, which pass through the slots F and re ceive the end of thecoupling-link J between them. The rear end of the coupling-link isprovided with an angular opening or perforation, and the lower ends ofthe lugs I are provided with similar angular perforations. Through theseperforations I insert an angular pin, K, having cylindrical ends, whichrestin 5.5

notches formed in the inner faces of the side walls of the draw-head,and form trunnions on which the pin and link swing in the operation ofthe device. The link J is a solid bar for the greater part of itslength, and at its front end it is provided with the longitudinal slotL,'which is engaged by the pin of the other coupling when two cars arecoupled.

When using my device, the pin and link of one coupling is raised and thepin and link of the other coupling islowered, as will be readilyunderstood from the drawings. The pin and link are so arrangedwithrespect to each other that when one is within the draw-head theother will be without the same, and the pin K,

being angular in cross section, serves to keep them in this position.

M and N are rods running to the top and side of the car respectively,and connected to the pin to operate the same, as will be readilyunderstood.

In operation the link of one coupling is engaged by the pin of theother. When the link strikes against the pin, the curved formation ofthe same will allow it to easily yield to the motion of the link andride over the end of the same to engage the slot therein. Should the pinor link be broken, the block E is re moved and the pin K disengaged fromthe rear ends of the link and pin. part is replaced by a new one, andthe several parts then returned to their normal operative positions.

'It will be seen that my device is cheap,

simple, and efficient, and can be operated with out the necessity of theattendant going be tween the cars and endangering his life.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-
